Visible-Light Driven C-P Bond Formation with Recyclable Carbon Nitride Photocatalyst

The development of metal-free chemical process with recyclable heterogeneous catalyst under ambient conditions is highly desired in industrial production, especially for pharmaceutical purpose. We herein reported the efficient synthesis of pharmaceuticall

Cu/Picolinamides-Catalyzed Coupling of (Hetero)aryl Halides with Secondary Phosphine Oxides and Phosphite?

Some 4-hydroxy-picolinic acid derived amides were revealed as more efficient ligands for Cu-catalyzed coupling of (hetero)aryl halides with secondary phosphine oxides and phosphites. Only 3—5 mol% CuI and ligands were required to ensure coupling with a number of (hetero)aryl bromides and iodides to complete at 120 oC in 10—20 h.

Visible-light-induced ligand-free RuCl3 catalyzed C-H phosphorylation in water

Visible-light-induced C-H phosphorylation of para-CAr-H and heteroarenes was realized using cost-effective RuCl3 as a catalyst. The reaction conditions are green and environmentally friendly, using water as a solvent at room temperature and without ligands. A broad range of highly functional organophosphorus compounds were obtained via a cross-dehydrogenation-coupling (CDC) reaction. In addition, we also proved that RuCl3 is a photocatalyst via its absorption spectrum and on/off light experiments.

Manganese-Catalyzed and Mediated Synthesis of Arylphosphinates and Related Compounds

The free-radical arylation of H-phosphinates and related compounds was examined. A practical catalytic process with the air as the oxidant could not be found. However, an inexpensive and robust methodology was developed, using catalytic Mn(II) as the radi

Non-Doped Deep Blue and Doped White Electroluminescence Devices Based on Phenanthroimidazole Derivative

A novel deep-blue emitter PhImPOTD based on phenathroimidazole was synthesized, which is incorporated by an electron-donating dibenzothiophene unit and electron-withdrawing phenanthroimidazole and diphenylphosphine oxide moieties. Furthermore, the weak π–π stacking and intermolecular aggregation render the photoluminescence quantum yield is as high as 0.34 in the solid state. Non-doped organic light emitting diodes (OLEDs) based on PhImPOTD emitter exhibits a low turn-on voltage of 3.6?V, a favorable efficiency of 1.13?cd A?1 and a deep blue emission with Commission Internationale de l’Eclairage (CIE) coordinates of (0.15, 0.08). The CIE is very close to the NTSC (National Television Standards Committe) blue standard (CIE: 0.14, 0.08). PhImPOTD is also utilized as blue emitter and the host for a yellow emitter (PO-01) to fabricate white organic light-emitting diodes (WOLEDs). This gives a forward-viewing maximum CE of 4.83?cd A?1 and CIE coordinates of (0.32, 0.32) at the luminance of 1000?cd?m?2. Moreover, the single-carrier devices unambiguously demonstrate that typical bipolar-dominant characteristics of PhImPOTD. This work demonstrates not only that the phenanthroimidazole unit is an excellent building block to construct deep blue emission materials, but also the introduction of a diphenylphosphine oxide deprotonation substituent is an efficient tactic for harvesting deep-blue emitting devices.

Solid-phase cyclopalladation in S,C,S′-pincer systems: Rising alternative for synthesis in solution

In pursuit of a new and simple approach to complex organometallic systems, the possibility of formation of a palladium-carbon bond in the solid state via direct cyclopalladation has been studied toward several S,C,S′-pincer ligands with thione sulfur donors of different nature. It is found that mixtures of the ligand and PdCl2(NCPh)2 obtained by the manual grinding of reactants in a mortar efficiently undergo solid-phase cyclometalation upon heating in open test tubes without the addition of a solvent to afford the desired pincer-type products in high yields. In the case of the most active bis(thiocarbamoyl) ligand, solid-phase cyclopalladation proceeds even at room temperature. For the challenging bis(thiophosphoryl) derivative, the preformed non-metallated complexes can be successfully used as a starting material to essentially enhance the yield of the desired pincer complex compared to the conventional synthesis in solution. The solid-phase transformation is followed by IR spectroscopy and SEM analysis. The results obtained show that the suggested solid-phase methodology can serve as a powerful alternative to conventional synthesis of pincer complexes in solution. This journal is

Ni(II)/Zn catalyzed reductive coupling of aryl halides with diphenylphosphine oxide in water

P-Arylation in water has been developed via cross-coupling of aryl halides with diphenylphosphine oxide (Ph2P(O)H) and (RP)-(-)- menthyl benzylphosphinate catalyzed by NiCl2?6H2O/Zn under relatively mild conditions.

One-pot palladium-catalyzed phosphination of aryl iodides with Ph2PSnR3

We found a very efficient one-pot phosphination reaction starting with Ph3P, which by reaction with Na metal in liquid ammonia gives Ph2P- ions that reacted with R3SnCl to afford (trialkylstannyl)diphenylphosphine. The palladium-catalyzed coupling reaction of these stannanes with aryl iodides yield functionalized phosphines in high yield (69-97%). The use of Ph3P as starting reagent, the endurance of the reaction to a wide variety of functional groups and the easiness of a one-pot reaction make this method a useful and versatile approach to tertiary phosphine oxides.

N-aryl-3,3,3-trifluoro-2-hydroxy-2-methylpropanamides: K(ATP) potassium channel openers. Modifications on the western region

A subset of antiandrogen compounds, the N-aryl-3,3,3-trifluoro-2- hydroxy-2-methylpropanamides 1, were found to activate ATP sensitive potassium channels (K(ATP)) and represent a new class of potassium channel openers (PCOs). A structure-activity relation

synthesis and Solid-State Structure of Substituted Arylphosphine Oxides

We described the preparation and characterization of several new arylphosphine oxides, which are of interest as second-order nonlinear optical materials. (4-Aminophenyl)diphenylphosphine oxide (1a), bis(4-aminophenyl)phenylphosphine oxide (2a), and (4-aminophenyl)bisphosphine oxide (5) were prepared by addition of aryl Grignard and organolithium reagents containing protected amines to phosphorus oxyhalides.Alternatively, 1a was prepared by treatment of (4-bromophenyl)diphenylphosphine oxide with azidomethyl phenyl sulfide, followed by hydrolysis. (4-Aminophenyl)(4'-nitrophenyl)phenylphosphine oxide (6) was prepared by nucleophilic aromatic substitution of bis(4-fluorophenyl)phenylphosphine oxide to give the corresponding dinitro compound, followed by selective mono-reduction.The X-ray crystal structure of (4-aminophenyl)diphenylphosphine oxide (1a), along with those of mono-, di-, and trihydroxy triphenylphosphine oxides 1b, 2b, and 3b, exhibit extensive intermolecular hydrogen bonding.The hydrogen bonding in 1a and 1b produces chains of arylphosphine oxide molecules with a head-to-tail alignment; the chains pack in an antiparallel manner to produce solid-state structures that display only slight deviations from centrosymmetry.
